Abstract
Paper covers the researching the process of fluid flow in the reservoir in the fracture-porous reservoir based on mathematical modelling. The model of the dual porosity of Warren and Root was used. The model has two pore systems - a system of fractures and a system of matrices with different values of geometric dimensions and filtration-capacitive properties. The pressure distribution in the "system of fracture-matrix" system is described by the piezoconductivity equations. The paper presents a numerical solution of the problem under consideration. Рartial differential equations were approximated using an implicit difference scheme. The matrix sweep method was used for the calculation. Model pressure recovery curves were obtained. Analysis showed that the specific conductivity coefficient depends on the size of the matrix blocks and possible to evaluate the process of manifestation of the effect of dual porosity.
